On that note, I just pulled my 'primary' sending unit (the one attached to the main fuel pump) out and checked resistance. It's shot. I'll be ordering another one and replacing it. What led me to check it was some extremely sporadic gauge readings. I'll let y'all know what I find.

I didn't check the secondary one since this one was so... broke. I may check it if readings are funny after I replace the first one.

I'd also appriciate the links. I'm having the same problems. My gauge will read 3/4 of a tank at one point in the day when I knew the tank was full (I just filled it up 20 minutes ago), and about 6 hrs later it went up to full as I pulled into the driveway.

Yeah, my gauge is crap. I've been right above E and at half a tank and filled up and still had to pump in 9 or so gallons. The best way to judge is figure out how many miles your getting in a tank. I get about 200-220 depending on how hard I am driving the car. At which point I need to fill about 9-9.5 gallons.
